To save energy, light mode + dim screen or dark mode + bright screen?

Question

I find myself increasing my screen brightness whenever I use dark themes/modes, and vice versa. Since I have no real preference between the two, I'm thinking of just choosing based on energy savings.Which combination saves more energy in the long run?

AFAIK, dark mode can save energy on OLED based screens (due to pixels being completely turned off) but not on LCD-based screens. However, lowering brightness should probably always lower energy usage.

I was going to give an opinion but wouldn&rsquo;t it be more fun to make an experiment?
